The numeric comparison operator evaluates its operands

   

#returning a -1 if the first operand is less than the second operand, 
#             0 if the numbers are equal, or 
#             1 if the first operand is greater than the second.

$x = 5;
$y = 4;
$result = $x == $y;
print "$result\n";

$result = $x != $y;
print "$result\n";
$result = $x <=> $y;
print "$result\n";

$result = $y <=> $x;
print "$result\n";
